To all 'whom t may concern.' Y 1 Be it known that I, AARON LEROY SMART,a citizen ofthe United States, residing at Vickery, in the countyv ofrSandusky and State of Ohio, have inventedinewv and useful Improvementsin Vrenches, of which the followingV is a specification-,f i p "1 `Thepresent.' invention relates toA improve-V mentsin: wrenches voftheratchet type, and the primary 4object of the invention is toprovide fa.ratchet mechanism for. such wrench including. a dog designed vktoengagebetween the teeth of the turning member .ar-1 ranged upon theV head of'athe'-` .wrench wherebywhen such dog is swung to either side of thewrenchitzis brought into suoli eugagement as to be effectively held inoperative position, butatthe Asame time permi'tting of the said dogfreely ratcheting over i1 the teeth of the turning member.

With the above and other objects in view the improvement resides intheconstruction, combination and arrangement of parts set forth in thefollowing specification and falling within the scope of the appendedclaims.

1n the drawings:

Figure 1 is a plan view of 'a wrench constructed in accordance with thepresent invention,

Fig. 2 is a side elevation of the same,

Fig. 3 is a sectional view approximately on the line 3 3 of Fig. 2, y

Fig. 4 is a sectional view approximately on the line 4-4 of Fig. 1, y

Fig. 5 is a perspective view of the dog,

Fig. 6 is a similar view of the spring pressed bolt which co-engageswith the dog,

vand n Fig. 7 is a perspective view of the turnable member or sockethead. n

Referring now to the drawings in detail the wrench is broadly indicatedby the numeral 10, the same including a handle 11 which in plangradually increases in width from one of its ends to its opposite end,and the widened end 12'is provided with a round aperture 13. The handle11 from kits widened end is bifurcated for a suitable distance, and theend wall 14 provided by the specificati@ 'of Letta-gratuit] ,ricamiJA{iiiiaoiv LEROY siviiinfr, .orvioirsiur,n oiiio.

thiCkness equallingY the distance between the inner `walls provided bythe slot or bifurca tionjinth'e handle, and the said, member 18v isvperipherally provided.v with spaced teeth 19.

Pivotally secured as at'i20, between the e arms provided bythebifurcated portionof the-wrenclnwherebyfto permit of the socket memberturningpin a .desired direction and prevent-the turning ofthe saidsocket mem ber in an opposite direction. The body` of the dog 20 iscentrallyfwidened, gradually decreasing in width to the engaging ortoothed endsthereof, and the said body, to the rear of the pivot, isprovided .with a substantially V-shaped depression 23, and the innerwall of the said depression is centrally provided with an aperture V24.This aperture is designed to receive the offset end 25 of a bolt member26, the opposite or free end of the said bolt passing through theaperture 15 and entering the pocket 16. The bolt at a suitable distancefrom its offset end 25 is provided with transverse lugs 27, and the bolthas arranged thereon a helical spring 28 which is designed to exert apressure Vbe-` tween the wall 14 and the lugs 27. When the dog 21 isswung to bring one of its active faces or tooth in engagement betweenthe teeth of the socket member 17 the bolt 26 will be brought tocontactwith one of the side walls provided by the V-shaped depression 23, andtherefore vout of longitudinal alinement with the pivot 20 of the Saiddog. The bolt having one of its ends contacting with oneof the sidewalls provided by the V-shaped depression 23 in the dog 21 anditsoppositefend frictionally contacting with the opposite walls providedby the aperture 15 will be held against further angular movement, and.consequently hold the active endV of the dog in proper position withrespect to the toothed portion 19 of the socket member 17.

'Having thus described the invention, what I claim is: Y j

1. A wrench including a handle having a toothed socket member journaledthereon, a dog. centrally pivoted to the handle, and designed to beswung to either side of the yhandle to engage between the teeth kof thesocket member,'said dog having a ,V-shaped depression opposite and tothe rear of its pivot, and the inner Wall provided bythe depressionhaving anV aperture, a spring pressed bolt having kan offset endreceived in the aperture, the handle'having a pocket n provided with arestricted opening through which the free end of the bolt'. enters thepocket, and the .said bolt :adapted to be brought in locking engagementwith the opposite walls provided by the restricted opening, when thepocket is swung to bring the t naled in the round opening ofthe handle.t and having a central enlarged portion provided with spaced teethreceived in the bifurcation of the handle, the inner Wall of thebifurcation having an aperture, the said handle having apocketcommunicating with the aperture, a centrally pivoted dog in thebifurcated portion of the handle designed to be swung to either side ofthe handle to engagewith the teeth of the socket member, Said dog to therear of its pivot having` a l-V-shaped depression and the inner wall ofthe depression having an aperture at the juncture of the `angular wallsof `thedepressiom abolthaving an angular end received in the apertureand designed when the dog is swung to engaging position to Contactl withone of the side walls of the V-shape'd depression,` .offset lugs uponthe bolt, the free end of the bolt passing, through the aperture'in theend wall of the bifurcation of the handle and enteringthe pocket, and aspring member uponxthe bolt exerting a pressure between the end walll ofthe bifurcation and the lugs upon the bolt.

In testimony whereof I a'lhx my signature.

AARON LEROY SMART.
